HP-UX 11i Version 2 Release Notes (October 2003)

Disk and File Management
VERITAS Volume Manager (VxVM) 3.5
Chapter 5
120
• Disk group import times are faster, due to improvements in object indexing and new
code which improves I/O bandwidth usage while validating the on-disk configuration
copies. All configurations notice faster import times, but large configurations
experience the most dramatic improvements. If existing large disk groups are
combined, the results are even more impressive.
• System management commands like vxprint and vxstat run in a fraction of the
time, and have less impact on other operations.
• Modifying existing objects with commands such as vxedit, vxmend, and vxdisk
takes less time. In large configurations, operations are almost instantaneous instead
of taking up to half a minute.
• Now any system configuration can reach the maximum I/O throughput of the system
without approaching any VxVM limitations. Large numbers of parallel
resynchronous operations no longer have a significant effect on other administrative
commands.
Compatibility
For a compatibility issue related to the support of larger file systems, see “Usage of
ustat(), statfs(), and statvfs()” on page 199.
Performance
There are no performance issues.
